CORNER-LOCK FOR BEDSTEADS.

Application led March 13, 1918.

To all whom t may concern.'

Be it known that l, DARRELL F. DYKE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Corner-Lock for Bedsteads, of which thefollowing is a speciiication.

This invention relates to improvements in corner locks for bedsteads,and has particular reference to that class of corner locks adapted forlocking angular metal side and end rails to wooden posts, although, aswill hereinafter appear, the invention is applicable to met-al posts aswell.

The objects of the invention are to produce a simple and inexpensivedevice or lock particularly adapted for application to the wooden postsof a bedstead whereby the angular end and side rails may be applied ineither of their two positions and securely and rigidly locked inposition.

Various other objects and advantages of the invention will hereinafterappear, and the novel features thereof will be particularly pointed outin the appended claims.

Referring to the drawing:

Figure l is a side elevation and partial central vertical section of awooden post, side rail and pillar-plate constructed in accordance withmy invention;

Fig. 2 is a vertical transverse sectional view of the same on the line2-2 of Fig. l; and

Fig. 3 is a detail in front elevation of the pillar-plate.

In practising my invention, I construct the rail l, of angle-iron,bending the same near its ends to form right angular or downturnedextensions 2. This is preferably ac complished by the removal of atriangular piece of metal from the vertical web, 3, of the rail neareach of its ends and subsequently bending the horizontal web, 4t, atpoints coincident with the apices of such triangular recesses as areproduced by the removal of the metal described. The bending of the railnear its ends will, of course, bring the two edges of the recesstogether, so that the rail is not materially weakened. To reinforce thevertical web of the rail at these points, the triangular piece of metalremoved, as described, may be utilized by being applied and riveted tothe vertical web of the rail,

Specification of Letters Patent.

Serial No. 222,075.

The down turn portion or end of the horizontal web of the rail isprovided with a centrally located perforation 5, and above and below thesame and in line therewith with apertures 6.

'i' designates a pillar-plate, and the saine is formed of sheet-metaland adapted to be applied to a wooden or other post, 8, of a bedstead.The rear side of this plate, in the present instance, is flat, tocorrespond with the external surface of the post, but it will beunderstood, that the rear-face of thc plate may be otherwise shaped inaccord-ance with the design of post with which it is to be used.

rllhe plate 7, within its edges, is provided with an elevated portion orface 9, and at the four corners of such counter-sunk screw holes 10 areformed. @rdinary wood screws ll, are passed through these holes and intothe post, whereby the pillar-plate is firmly secured in position. Aswill be obvious, boltsV may be substituted for the screws if it bedesired to employ this lock in connection with metal instead of woodenposts.

At the center of the raised portion of the plate is punched arectangular or other angularly shaped opening l2, the purpose of whichis to receive the angular portion 13, formed at the base of a bolt orstud 14;, adjacent to the head l5, thereof. The head l5 of this bolt ispositioned in rear of the raised portion of the pillar-plate andsubstantially agrees in thickness with such raised portion, so that whenthe bolt is in position in the pillar-plate the head of the bolt willbear against the post and hence, as will be obvious, the post will notrequire recessing to receive the head. Above and below the angularopening l2 in the pillar-plate and at equidistant points therefrom, thepillar-plate, or rather, the metal of which the saine is formed, isdrawn outward so as to produce rounded lugs or teats 16, the same beingcoincident with the apertures 6, formed in the down-turned extensions ofthe rail and heretofore mentioned.

In operation, the pillar-plate being positioned and secured upon Ithepost by the screws 11 or their equivalents, the rail is abutted againstthe saine and in such manner that the lugs or teats 16 will enter theaperture 6 and the stud or bolt will enter and pass beyondthe opening12. In' order to secure the rail rigidly to the pllar-plate it is nowonly necessary to apply to the outer threaded end of the bolt a nut 17,which may be of the form shown or of the winged variety. It will beobvious that the vrail may be readily removed from the pillar-plate bysimply removing the nut and withdrawing the rail; also that when thusclamped in position by the nut the rail will be prevented from turning.The lugs 16 and the apertures 6 being equidistant from the stud or bolt14 and the hole 12 that receives it, it will be clear that the positionof the rail may be reversed from lthat shown in the drawing, or, inother words the horizontal flange of the rail maybe positioned at thelower instead of the upper side of the rail, and thus, vas is verydesirable in beds, the mattress support may be raised or lowered.

From the foregoing description it will be obvious that 'I have producedan extremely simple and rigid connection between rails and posts, andone that can be produced from sheet-metal at a comparatively low cost.

Having described my invention, what I claim is: l
